New Features User Tagging Feature Just Added

I'm playing with a new feature today, it's called Advanced User Tagging, and you can just do something like put the "@" sybmol in front of someone's name, like TrailLeadr and then you can tag them in a post and they will be notified that they were just tagged. So, hey [MENTION=11022]TrailLeadr[/MENTION], you've been tagged. You too [MENTION=13060]Cableguy[/MENTION] and all of you other old timers. [MENTION=46008]Steve T[/MENTION]oo, gonna try it myself to see what happens.
